3M 7100000490 Convolute Deburring Wheel 8 Inch

Product Description

The 3M 7100000490 is a convolute deburring wheel built for aggressive edge work and surface finishing on metal parts. The wheel is constructed with aluminum oxide abrasive bonded into a convolute configuration, which layers the abrasive material in a wound structure for consistent cut and long service life. At a density rating of 5 with a medium grade, it delivers enough aggressiveness to remove burrs, sharp edges, and light scale without excessive stock removal. The 8-inch diameter and 1-inch face width suit it to bench-mounted backstands and inline production setups. Maximum rated speed is 4,500 RPM.

This wheel is intended for metal fabrication and finishing applications in industrial and shop environments. It suits operations where repeatable edge conditioning is required across high part volumes. Compatible tooling includes backstands, manual backstands, pressure assist backstands, centerless grinders, die grinders, and inline sanders. It is sold individually and is a direct fit for facilities running standard 3-inch arbor spindles on any of those machine types.

Key Features

• Aluminum oxide abrasive provides durable, consistent cut on ferrous and non-ferrous metals
• Convolute construction delivers uniform abrasive density throughout wheel life
• Density 5 medium grade balances cut rate with surface finish quality
• Rated to 4,500 RPM for safe use on standard backstand and grinder setups
• 8-inch diameter with 1-inch face width suits production backstand applications
• 3-inch center hole fits standard industrial arbor sizes

Compatibility

Designed for use with backstands, manual backstands, pressure assist backstands, centerless grinders, die grinders, and inline sanders equipped with a 3-inch arbor.

Installation Notes

Installation and wheel changes should be performed by a qualified operator following machine manufacturer guidelines and applicable ANSI B7 safety standards for abrasive wheels. Always power down and fully de-energize the machine before mounting or removing the wheel. Inspect the wheel for cracks or damage before each installation and never operate above the rated 4,500 RPM. Ensure the arbor flange and blotters are in good condition and that the center hole seats properly on the spindle before running.
